Does anyone know how to convert a quaternion attitude into a roll,
pitch, yaw (in this order) and the yaw, pitch, roll (in this order)
for a 'NASA Standard Aircraft'?

http://www.euclideanspace.com/maths/geometry/rotations/euler /index.htm

I was trying to use Rick's quaternion code which pitch about x, yaw
about y, and roll about z but x and z are swapped. My naive was to
simply swap the pitch and roll on input/output but I cannot seem to
reproduce the given tables:

Given that it is now very, very late and I've wasted a good few hours
trying to figure this out, I think it is time to call upon the IDL
experts...

Thanks,
Graham
